The Chelsea 880 Series Power Take-Off Assembly, part number 880XJAHX-A5AZ or 880XJAHXA5AZ, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications on manual transmissions from Eaton/Fuller, Volvo/Mack, and Allison. The output shaft is a 1-1/2"-10T spline fitted with a 1410 companion flange, supporting intermittent torque up to 500 lb-ft (678 Nm). Shaft power runs 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing carries tapered cone bearings for load bearing, and the removable shift cover allows backlash adjustment without pulling the unit. A dual-pump output lets you mount a hydraulic pump on each end. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks. Call us to confirm proper fit for your transmission.
The Chelsea 880 Series is suited for demanding on-highway and off-highway work including bulk haulers, fire trucks, aerial equipment, oil field machinery, winch systems, and large truck recovery. The 880 Series supports continuous operation with a 30% de-rating and is available with multiple output flange and spline configurations across the series. Refer to Chelsea application pages to confirm the exact torque rating for your specific transmission and RPM range.
